Abstract
A flow meter consists of calculation display, connection tube and meter body as vortex generator is erected on fluid channel in meter body with electrode and magnetic steel set at downstream of vortex generator.
Description
Affiliated technical field
The present invention relates to a kind of electromagnetism swirl flowmeter.
Background technology
At present, there is the manufacturing process complexity in known electromagnetic flowmeter on the market, cost height, the deficiency that power consumption is big; There is lower limit flow velocity height in known swirl flowmeter, is subject to the shortcoming that pipe vibration disturbs, and has influenced being extensive use of of above-mentioned two class instrument.
Summary of the invention
The present invention provides a kind of simple in structure in order to overcome the deficiency that above-mentioned electromagnetic flowmeter or swirl flowmeter exist, and saves material, and is low in energy consumption, detects accurately, and anti-vibration can be surveyed the electromagnetism swirl flowmeter of very low current limliting speed.
The technical solution adopted for the present invention to solve the technical problems is, a kind of electromagnetism swirl flowmeter, comprise integrating display instrument, connecting pipe, table body, on the fluid passage in the described table body vortex generation body is housed, the downstream of vortex generation body is provided with electrode and magnet steel, magnet steel.
One end of described electrode is connected with an end of connecting link, and the other end of connecting link stretches in the connecting pipe, makes electrode vertically be in the middle part of the fluid passage of table body.
Described magnet steel is located on the upper wall and lower wall of the table body vertical with center lines of electrodes with magnet steel, and electrode is in the magnetic field of magnet steel and magnet steel generation.
Described connecting link traverse stretches into the fluid passage of table body, and with the fluid passage parallel axes, an end of connecting link is connected with electrode one side towards downstream, and the other end of connecting link is connected on the lateral wall of fluid passage outlet.
The invention has the beneficial effects as follows, excitation mechanism with the magnet steel replace complex can be saved wide variety of materials, improves anti-seismic performance, and is more accurate more, reliable than the variation that detects magnetic flux flux period with electrode detection, and can survey very low current limliting speed, enlarge measurement range.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples.
Fig. 1 is the structure cut-open view of the embodiment of the invention 1 electromagnetism swirl flowmeter;
Fig. 2 shows the sectional elevation of body along the A-A line among Fig. 1;
Fig. 3 is the longitudinal section of the table body of the embodiment of the invention 2 electromagnetism swirl flowmeters;
Embodiment
Embodiment 1:
As Fig. 1, shown in Figure 2, the integrating display instrument 1 of present embodiment electromagnetism swirl flowmeter is contained in the upper end of connecting pipe 2, the lower end of connecting pipe 2 is contained in the middle part of table body upper wall 9, one end of electrode 4 is connected with an end of connecting link 5, the other end of connecting link 5 stretches in the connecting pipe 2, make electrode 4 vertically be in the middle part, fluid passage of table body 3, magnet steel 6 is located on the upper wall 9 and lower wall 10 of the table body vertical with electrode 4 center lines with magnet steel 7, produce a magnetic field around making 7 pairs of electrodes of magnet steel 6 and magnet steel 4, on the fluid passage of electrode 4 upstreams, vertically lay vortex generation body 8, when fluid during by vortex generation body 8, the bumpy flow that produces is cutting magnetic line downstream, cause the variation of magnetic flux, detect the flow that can accurately reflect fluid flux period, show through integrating display instrument 1 by electrode 4.
Embodiment 2:
As shown in Figure 3, part identical with embodiment 1 in the present embodiment electromagnetism swirl flowmeter no longer repeats, connecting link 5 traverses stretch into the fluid passage and the fluid passage parallel axes of table body 3, one end of connecting link 5 is connected with electrode 4 one side towards downstream, the other end of connecting link 5 is connected on the lateral wall 12 of fluid passage outlet 11, fluid flows out from channel outlet 11, and the advantage of this embodiment is to have eliminated the resistance that this vertical component convection cell produced when connecting link 5 vertically was connected with electrode 4.
The above is a preferred implementation of the present invention, should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the principle of the invention, can also make some modification and improvement, and these also should be considered as belonging to protection scope of the present invention.
